through German Shepherds I used to breed back home (knowing who to breed to get the correct colouring or to correct defects within the parents - ie breeding puppies to better the breed)....

But generally, even if the mom had been having an affair with some who was white... the genes from the mother would have come through much more than they have... which seems like almost zilch...

This is truly strange.... hmmmm... me thinks there is way more to this story....
